We examine the relationship between product liability litigation and innovation by systematically combining data on product liability lawsuits with data on new product introductions in a panel dataset of leading medical device firms. We first document a decline in the propensity to introduce new...

In this article I first describe the basic principles that parents employ in disciplining their children. The description is based on a survey of parents, the major results of which are that parental sanctions are premised on wrongdoing--not on the mere causation of harm; that parental sanctions...

The primary causal requirement that must be met for a negligent party to be held liable for a harm is a demonstration that the harm would not have occurred if the party had not been negligent. Thus, for a speeding driver to be found liable for harm done in a car accident, it must be shown that...

What causes adverse policing outcomes, such as excessive uses of force and unnecessary arrests? Prevailing explanations focus on problematic officers or deficient regulations and oversight. Here, we introduce a new, overlooked perspective. We suggest that the cognitive demands inherent in...

We document a sharp rise in gunshots coupled with declining 911 call volume across thirteen major US cities in the aftermath of the murder of George Floyd. National survey data also indicate that victims of crime became less likely to report their victimization to law enforcement due to mistrust...

Do jobs and income-transfer programs affect crime? The answer depends on why one is asking the question, which shapes what one means by "crime." Many studies focus on understanding why overall crime rates vary across people, places, and time; since 80% of all crimes are property offenses, that's...
